Idk y this is in the polar bear section.
This is a reference to SRS (Sex Reassignment surgery) basically saying that it is easier to take away (erectile tissue) and create a vagina vs make erectile tissue and create a penis.
In school, pulleys are used to put up a flag. That's a lot easier than climbing the pole just to raise a flag!
Ozone layer is depletion is happening in the stratosphere of the earth's atmosphere. It is majorly concentrated over Antarctica's atmosphere.
Yes. It is smaller than the southern polar ozone hole. There is a hole that forms in the ozone layer above the pole that is experiencing winter. The Southern pole get more hydrogen nucleii form the solar wind than the northern pole does, due to Earth's current magnetic field arrangement. This is why the southern polar hole is larger than the northern polar hole.
yesbut in some parts theres no hole but the ozone is too thickThe ozone hole this (2009) winter/spring (south pole) was a little smaller than the record size. Whether Man had any part in that "improvement" through his efforts remains to be seen. Note that the ozone hole is an annual repeating phenomenon at each pole, and the southern ozone hole is naturally larger than the northern ozone hole.
There is a smaller ozone hole at the North Pole, but the hole in Antarctica is largest because the South Pole is much colder than the North Pole (-80 C). CFCs released from industries take several years to rise to the stratosphere and global winds spread these man-made gases all over the world. The extreme cold in Antarctica provides ideal conditions for the chlorine in the CFCs to separate and destroy the ozone. See the question below for more.
Cars and dishwashers make my life easier than if I didn't have them.
An ozone hole forms when there is no UV-C from the Sun to replace the decay of ozone (both natural and man-caused). This occurs when the pole is having winter.Antarctica's hole (South pole) is larger than the arctic hole (North pole), because the Earth's magnetic field directs positive charges from the solar wind to it, which is primarily hydrogen, and hydrogen oxidizes to water vapor, which decays ozone. The north pole gets almost exclusively electrons, which tend to make a bit more ozone, although indirectly.See "Why is an ozone hole formed only above Antarctica and not over developed countries that emit a lot of CFCs?" in the "Related questions" section below.
Compasses make the job much easier!
A fiberglass flag pole can better withstand the natural elements such as wind, sun exposure, and rain. It is also easier to clean and maintain.
Yes
It is much easier to make plastic from petroleum than from milk, just as it is much easier to make ice cream from milk, than from petroleum.
